To put words into equations:
x+y+z	=50
x=4y
4y=5z -> z= 4/5 y
Which means
4y+y+ 4/5 y= 50
29/5 y =50
29y=250
Y=29/250
        
             
        
        
        
Answer:
y = 259.6/2 = 129.8 degrees. so x = 129.8 - 79.6 = 50.2 degrees.

Answer:
 72
Step-by-step explanation:
Let the number of candies = n 
Tracy ate = 1/3 of n = n/3 remaining 2n / 3
she gave 1/4 of the remainder to her friend = 1/4 of ( n - n/3) = 2n / 12 
the new remainder = (2n / 3) - (2n / 12) = n /2 
she and her mom then ate altogether = 30 
and the brother took from 1 to five, the number he took = x 
and she has 3 left 
( n/2) - 30 - x = 3 
 n = 2 ( 33 + x) 
now we know that the candies could not be broken  and x is between 1 to 5 
n = 2 (33 + 1), 2 (33+2), 2(33 +3), 2 (33+ 4) and 2 (33 + 5) this are the possible values of n, ( 68, 70, 72, 74, 76) and the multiple of 3 is 72 
n therefore = 72
 
        
             
        
        
        
Answer:
6g -3g +6g -3g = 5+6-11-3+5-11
6g=-18 
6g= -18 /÷6
g= -3
